This shoe rack is perfect. It's so big, and you can absolutely fit 30 pairs on it! It is also lightweight and easy to put together. I was worried it wouldn't be sturdy since the pieces are all hollow metal tubes, plastic connectors and fabric shelves but it's surprisingly very sturdy. Seems like it will hold up really well. 

You can't really fit boots in the shelves so I put mine on the top one, which works great since I don't have many. Might also be a little less ideal for heels but works perfectly well for sneakers, sandals, and flat dress shoes. I am so happy with this purchase.
